Abstract:

Objective

To compare the esophageal motility and the levels of brain-gut peptide between refractory globus patients and non-refractory globus patients.

Methods

All subjects underwent high-resolution manometry (HRM) and were detected the levels of brain-gut peptide, which were compared the differences between refractory globus patients and non-refractory globus patients.

Results

Refractory globus patients had higher upper esophageal sphincter (UES) resting press [(94.97±42.08)mmHg] compared with non-refractory globus patients [(73.91±23.47)mmHg, t=2.359, P<0.05]. There were no statistical differences in UES residual pressure[(12.44±8.31)mmHg, (12.66±8.12)mmHg], UES length[(22.72±10.13)mm, (19.71±7.85)mm], CFV[(5.47±1.39)cm/s, (5.24±1.40)cm/s], DL[(6.59±1.29)s, (6.78±1.10)s], LES[(22.63±10.17)mmHg, (19.56±7.63)mmHg] between refractory globus patients and non-refractory globus patients (t=0.528, 0.471, 0.725, 0.736, 0.486; P>0.05). The level of NPY was lower in refractory globus patients [(626.26±16.60)ng/L] than that in non-refractory globus patients [(641.35±17.45)ng/L (t=2.528, P<0.05)], but the level of SP was higher in refractory globus patients [(2386.96±372.68)ng/L] than that in non-refractory globus patients [(1607.77±345.91)ng/L], the difference was statistically different (t=3.728, P<0.05). And no statistical difference was found in calcitonin gene-related peptide (CGRP) between refractory globus patients and non-refractory globus patients (t=0.752, P>0.05).

Conclusion

Compared with non-refractory globus patients, refractory globus patients have higher UES resting pressure, higher level of SP and lower level of NPY.
